Contractor: Butt Construction Project: Sub-element Chamber - Structures Research Laboratory at Wright Patterson A.F.B.
Location: Dayton, Ohio Date: Summer 2002-2003

Project Manager:  Chuck Cheadle    Project Engineer:  Josh Finberg    Concrete Superintendent:  Ed Shell

Notes:

The horn tapers from 84" inside dimension at the large end to 12" in  its 16' length.  The requirements for a smooth finish on the inside of the horn were very important.  Because of the small tapered end, it would be difficult to perform any remedial concrete patching on the inside of the  structure.

The attached pictures show the structure being removed from  the forms by a 75 ton overhead crane located in building 65 at Wright-Patterson  AFB.  The structure was turned 90 degrees in the air and set on the ground.  It was then dollied into place inside a large acoustical chamber in the Structures Research Laboratory at WPAFB

The completed sub-element chamber will be used to test experimental materials used in jets by subjecting them to sound waves at up to 150 dB.
